👉 Valvulitis is a condition in which the valves of the heart, especially those that control blood flow to the lungs and other parts of the body, become inflamed or damaged. This can lead to symptoms such as chest pain, shortness of breath, fever, chills, and fatigue. It's often caused by inflammation from viruses or bacteria, but it's also linked to certain medical conditions like heart disease, stroke, and autoimmune disorders.
